When properly designed and installed, plumbing systems will provide many decades of problem-free service. Careful corrosion engineering management, including attention to details such as materials selection, fluid mechanics, water-chemistry control, protective coatings, cathodic protection, and suitable material corrosion allowance, should ensure these materials comfortably survive their design life. However, actions during the construction or renovation of a building can have unintended consequences that can dramatically reduce the service life of plumbing systems.
Two of Canada’s architectural projects, Centre hospitalier de l’Université de Montréal (CHUM) Auditorium in Montreal and Havergal College Upper School in Toronto, are selected among the 11 winners in North America for their innovative use of copper.
Entries are open for the 2020 North American Copper in Architecture (NACIA) awards. Architects, designers, and sheet metal contractors can submit their building projects for consideration through January 31, 2020.
The Indian Residential School History and Dialogue Centre by Formline Architecture in Vancouver, B.C., is the recipient of the 2019 North American Copper in Architecture (NACIA) award in the ‘New Construction’ category.
During the restoration of a clock tower in Huntsville, Ont., the contractor uncovered significant deterioration within the multi-wythe clay brick exterior walls. The project was expanded to include: demolition of the deteriorated brick walls, reconstruction of the tower walls one corner at a time, replacement of the steel roof, and recladding of the tower exterior walls.
Green, patinated copper is the result of a natural aging process and has been coveted by architects and designers since ancient times. Copper does not react with water, but it does with atmospheric oxygen, forming a layer of brown-black copper oxide protecting the underlying metal.
When looking toward the sky in any major city in Canada and across North America, it is not uncommon to find a copper roof or wall cladding system. The metal has contributed to elaborate ornamental applications and complex architectural details on historic buildings for centuries, but why do architects and design teams continue to specify this material?
Until January 31, Canadian architects and sheet metal contractors are encouraged to submit their building projects for consideration in the North American Copper in Architecture (NACIA) awards program.
East of downtown Kingston, Ont., overlooking the St. Lawrence River and Lake Ontario, the Royal Military College (RMC) is notable for its blend of modern academic, athletic, and dormitory facilities, with century-old buildings.
